Classification of Wines Using Principal Component Analysis
Autor: Jing Cao, Jackson Barth, Chenyu Yang, Duwani Katumullage
Publikováno v: Journal of Wine Economics. 16:56-67
Classification of wines with a large number of correlated covariates may lead to classification results that are difficult to interpret. In this study, we use a publicly available dataset on wines from three known cultivars, where there are 13 highly
